[Cooker] Installer

[Andrew M]

I have one issue with the installer: colors. The default blue scheme can
be somewhat confusing (for example, small status boxes that pop up (like
in the partitioner), tend to get "camouflaged"). And I don't think
multiple themes for the installer are really necessary. How about just
creating one VERY clean theme? Dark lines on a light backround gives the
best contrast.
